<p>Att ta fram en ny bilmodell är ett tidskrävande och omfattande arbete där många olika kunskapsområden måste samspela. En del i utvecklingsprocessen som får allt större betydelse är designarbetet.

Abstract:
The process of design is time consuming and result oriented. There is always a better scope for any design that reduces the time with better precision. Considering this as a major factor during design process, two of the vital parts of the aircraft conceptual design are taken into account where a lot of time can be saved. Major components considered in this work are fairings for the lift generating surfaces and cockpit windshield. In this work the major inference is to reduce the time spent on the initial conceptual design. The two components designed in this work are fairings and windshield.

Abstract:
A presente investigação teve como propósito o estudo, recorrendo a análises numéricas, das características do escoamento num difusor de admissão em serpentina com elevada taxa de difusão e do aumento do rendimento do mesmo pelo uso de jatos em orifícios retangulares, a fim de que esta técnica de controlo possa ser considerada como uma solução ao problema do escoamento neste género de difusores. Para tal, dimensionou-se concetualmente um difusor ultracompacto, em serpentina, tendo em vista a baixa observabilidade de radar e de infravermelhos, com 0,45 metros de deslocamento vertical da linha ce

Abstract:
A continuing search for design methods pointing towards optimising flight overall efficiency renewed interests in unconventional design solutions for aircraft future demands. In line with several other unconventional designs, the development of morphing wing technologies for in-flight shape adaptation is one of the richest and most challenging interdisciplinary fields researchers have focused in recent years. A detailed guide on a telescopic wing design and sizing is presented, effects of design parameters on wing structural mass are investigated and a full mass predicting function is develope
